' .In a draft rigging,

the elements is normally prevented by the carry-iron 3 which must be removed before the coupler 1 may be turned to an angle permitting it to bediscngaged fro u the yoke.

The upper surface'of the coupler to the rear of the curved pivotal shoulder 16 is curved or beveled as indicated at .18, thus permitting the couplerto be swung verticallv or rotated about a transversely extending axis when being assembled or disassembled. In order to provide a suitable bearing surfacev 19 on the rear'end'of the coupler for en- 7 gaging the forward follower (not shown), 'the curved or beveledportion 13 of the coupler terminated somewhat above the longitudinal median lineof thecoupler and carriedby the coupler for preventing. rearward movement of the coupler with respect tothe-;yoke,'and means rigld with the car undenframe and directly engaging the .said

coupler,for maintaining the yoke and coupler-in interlocked relation.

. 3.. In avdraft rigging, the combination with a-draft, yoke having inwardly extending shoulders formed on the forward ends of its arms, of a coupler having shoulders adapted to cotiperate with the said shoulder on the yoke, said coupler andlyoke being detachable by a rotation of oneofsaid elements about a transversely extending axis passing between thearmsof said yoke.

. A; In a" draft jrigging,fthe combination with axdraft yoke, of a' coupler pivotally connected thereto, said coupler-being adapted to be inserted between the arms of said yoke at an angle thereto and to -be brought to assembled position by a movement in a plane at right'anglesqto the planes of the arms of said yok r 5. In a draft rigging, the combination with a draft yoke having arms of unequal length anda plurallty of shoulders, of a. cou- .;pler having a correspondingly shouldered end adapted to cooperate with the shoulders on the yoke, the said shoulders of theyoke arms being out of alinementtransversely. of theyoke. ,lj

i In a draft-rigging, the combination w th a draft yoke provided with inwardly 1 extending shoulders on the adjacent faces .of its arn'is, said shoulders being out of transverse alinement, of a coupler provided with correspondingly spaced shoulders, said 3 shoulders on the yoke'and coupler constltuting means for pivotally connecting said yoke and coupler. I

7. In a draft. rigging, the combination with a draft yoke provided at its forward end with'inwardly extending longitudinally spaced. lugs or shoulders the inner faces of which are curved; of a coupler provided with vertically extending shoulders, the said shoulderson the yoke and coupler constituting meansfor pivotally connecting the one to the other, the pivotal axis ofsaid coupler being located intermediate the said shoulders on the yoke arms. J 8. In a a draft rigging, the combination with a draft yoke provided with a hooded forward end and having an inwardly ex-- tending shoulder on each arm of the yoke adjacent its forward end, of a coupler pivotally connected to said yoke, said coupler having outwardly extending shoulders formed on its upper and lower faces, said shoulders on the coupler being adapted to pass between the shoulders on the yoke, the

said sets of shoulders being adapted to engage and form the pivotal connection between the yoke and coupler.

9. In a draft rigging, the combination with a hooded draft yoke having at the forward end of one of its arms an inwardly extending lug whose front and rear. faces are {concentrically curved, and having also at the forward end of 1ts other arm. an inwardly extending lug whose rear face is concentric with the curved faces of the first mentioned lug, of a coupler having shoulders whose forward faces areadapted' to respectively cooperate with the rear faces of the said yoke lugs to thereby form pivotal connection between said yoke and coupler, and means on the said coupler. engaging the forward curved face of'one'of the yoke lugs to prevent rearward movement of the coupler independently of the said yoke.

10. A draft yoke having arms of unequal length, each of said arms beingformed at its free end with an inwardly'extending shoulder adapted to extend in front of a corresponding shoulder of a coupler, said shoulders on the yoke being out of transverse alinement.

1 11. A draft yoke having inwardly extending lugs whose rear faces form concentrically. curved. segmental. pivotal bearings arranged on oppositesidesof their axis of curvature; 1 1''" 12. A draft yoke having the forward ends of its arms connected by bars whose forward edges extend obliquely to the arms of said yoke. said arms ,being provided with inwardly extendinglongitudinally spaced lugs adapted to engage the forward faces of correspondinglyvspaced lugs on a car coupler.

13. A coupler havingrconcentrically curved MLA coupler having at its rear end a bearing surface adapted to engage a follOWBIQ-Silld bearing surface belng of less extent than the rear end of said coupler and being of unequal extent on opposite sides of the longitudinal median line of the rear end of the coupler stem;

15. In a draft rigging, the Combination of 10 a coupler and yoke each provided with a plurality of rigidly attached members ada ted to'be interlockingly connected by a re a-' tive rotation, and means rigid with the car underframe for preventing the relative rota- 15 tion of said'members. 1
